Letters Patent N 101,719, dated April 12,1870.

IMPROVEMENT IN HARVESTERS.

The Schedule referred to in these Letters Patent and making part of thesame.

Be it known that I, RUDOLF EICKEMEYER, of Yonkers, in the county of\Vestchester alld State of New York, ,have invented certain new anduseful Iniprovenients in Mowilig and Ieaping-llachincs; alld I do herebydeclare lthat the following` is a `full and correct description thereof,reference heilig had to the accompanying .draavings and to the lettersof reference thereon.

The irst part of' lily invention relates to mechanism for giving motionto the cutter-bar, and consists in combining with the main axle or shaftof a mowing or rea-ping-nlachiue,'and the cutter-baloritspitnlan-counection, a lotating wheel which rotates witll the main axle,and an oscillating wheel which does not rotate but swings upon gilnbaljoints, the combination alld arrangen'ient of the lliechanisui heiligsuch, substantially as hereinefter described, tllat the lilotiollrequired for the cutter-bar is obtained by the action of the twogear-wheels.

My invention further consists ill a lever and lilikconnection with thepole aild linger-beam, whereby the cutting apparatus is first raised atthe outer end and then lifted 'at the heel and folded overand secured in'an' upright position, so as to be portable.

Also iu a lever-collllection with the sleeve below the drivers seat,whereby the driver may apply his weight to lifting the heel ot lthecutting' apparatus from the ground to avoid obstructions.

The drawings upon sheets 1, 2, and 3, represent the form of constructionI prefer for illy Improvements adapted to a mowing-machine.

The drawings .upon sheets 4, 5, and (i, represent modifications illconstruction adapted to rcapers and mowers.

I will llil'st proceed to describe the mowing-machine represented by thedrawings upon sheets 1, 2, and 3, of which- Figure 1 is a plan view ofthe mower.

Letters a a represent t-lle two driving and supporting-wheels.

a a', t-llc hubs.

b, the lliaill axle or shaft of the machine.

b IF, the pawl-lianges on the inaili axle, which couliect by pawls intheusual way with the driving-wheels, so that either or botlldriving-wheels operate the cutter-bar, the pawliiange l)l2 beingattached to and forniing a part of a bevel gear-wheel c; also fast tothe main axle, and 'rotating with it.

The sleeve d is loose oli the inain axle, ,and is moved upon itlongitudinally bya shifting-levcr,.d, alld a. clutch, d2, connecting bya clutch-groove, d, with the paul-flange Il', as sllowll ili thedrawings.

The bcvcl gear-wheel c gears ilito all internal bevelwhcel, c, whichdocs not rotate but oscill'ates upon opposite pills or studs, c c?, lig.5, fixed ill the hub j' of a vibrating arlll or lever, y, which itselfoscillatcs upolf two opposite pills, g1 yf, tig. 5, fixed inthe sleevealld extending ill opposite direct-ions ill bearings in the llllb. Thepill-joints of the hub of the vibrating lever alld of the lllib of theinternal toothed bevelwheel heilig at right angles to each other, agiuibal joint is forllled, which permits theoscillating bevelwhcel toroll on the gear of the rotating bevel-wheel, while the vibrating leverhas only a lat-eral vibration in straight lilies.

Ihe vibrating lever is connected bv a short link, h, to the cutter-barl.

The oscillating bevel gear-wheel c has one or two more teeth than therotary bevel gear-wheel o, so that, supposing the latter hasiii'tv-sixteoth and the former li'ljv-eigllt teeth, thc vibrating lcrorand cutter-bar will no iliade to vibrato twenty-eight tinics for everyrevolution of the llillill shaft or axle, which -is about the motionrequired for the cutter-bar.'

The lilies which form .the teeth in both gears, center in a point illthe axis ot' the nlaili shaft, which poilit is the conter of oscillationof the rgimbal joint.

The bevel-wheels should be so constructed that the .angle of vibrationof the oscillating bevel-wheel rllle oscillating bevel gear-wheel c1 hasarii'ls, c2 o" 0*,4 which extend inward toward the middle of theulachinc, and llliite ill a boss, c5, which receives the crank-pin i ofa fly-wheel shaft, 1"), which rotates ill a bracket-bearing,j, cast uponthe sleeve, and has allywllccl, Il', fast to the further end.

,l llc. oscillation ol' the bevel-gear cl imparts rotary nlotion to theily-wheel, the nulnberfoi1 revolutions corresponding to the number offull strokes .of the cutter-bar, as is the case in fly-wheels connectedwith otller 'cutter-bar motions in reapers and mowers, the object beingthe same, viz: to equalize the motion ol' the cutter, and protect thegear from sudden strains.

It will be observed that both the crank-pin alld flywheel shaft are illlines tllat intersect the center of oscillation of the gear-wlleel, theily-wheel shaft being thrown out of lille with the axis of the lnaillsha-ft or axle, to get room for the fly-wheel.

If desil'ed, the vibrating level' may be attaclled rigidly to theoutside of the gear-wheel, as in a modification hereinafter described,but in. sucll case the gimbal joint must he preserved by a ring illplace of the hub of the vibrating lever, pivoted to the sleeve inthesame manner, and tllcn the, construction will be inferior, because ofthe .compound motion tllerebygiven .to the end of the vibrating leverwllieh conllects with the cutter-bar pitman.

The cutting apparatus is hinged by the shoe, as usual, to a cast-ironframe or hanger, 7,/connected'to the sleeve by a wrought-iron bar, ga.,of suflicie'nt strength, the sleeve having a seat, 1j,east upon it toreceive the bar,-which is ,bolted thereto and tothe shoe-hanger l.byscrew-bolts, as is /shown ill the drawlugs.

The oscillating bevel gear-wheel isengaged with and released from ,thefixed yrotating bevel-wheel by moving the clutch shifter beforedescribed, the sleeve being free either to tllrn or move longitudinallyupon the main axle.

The drivers seat o is lixed upoll a wooden spring, p, jointed to thepole p at p2, the seat being placed behind tlle axle tolbalance thepole.

The pole is hinged to hangers or brackets, q q, cast on the sleeve andextending downward from the same about a quarter of-the radius of thesupporting-wheels, t0 relieve the shoe of part oi' the weight.`

A round rod, forms the hinge-connection hetween the pole-iron Il and thesleeve-hangers q q.

Beneath the sleeve, alld under the driver-s seat, so that he can restupoll it with his feet, is .a lever, s, made of round iroll bent ill theform shown in the drawings, which, being pivoted upon the pole hingerod1^', and the short ends resting on the sleeve, when pressed upon by theweight of the driver, turns the sleeve so as to lift the shoe ,of thecutting-apparatus, to avoid obstructions iu the line of the shoe.

The outer end of the linger-bar is lifted, to avoid obstructions, by thebent level' t, which connects with the shoe of the cuttill g apparatusby a rock-shaft, u, in theshoe-hanger, and segments of teetll al 'a2respectively placed upon the rock-shaft and shoe, so that, whenthe'lcvcr t is.moved toward the driver, the outemdof the finger-bar israised as described.

Thesaine'levcr is also collnected by a slotted lillk7 fe, with the pole,the slots in the link vsliding on the. headed pin el driven into thepole, and vthe connection with the lever being by a joint, 1:2, theconstrucion being such that when the lever is moved toward the driverthe slot in the link permits the outer elld ef the finger-bar to beraised without raising the inner end from the ground, until theA endof'tlle slot is reached, when the link is arrested by the pin","aud thebent lever finds a new fulcrum upon thel otller end of the link tllussupported by the pole, and the .operation of lifting the inner end ofthe eutting-lncch.

anism and the hinged frame commences, wllile at the same time thecutter-bar is folded 'in au Vupright position, as shown in the drawings,where it may be secured by a catch, w, upon the `standard w.

When the cutting apparatus is in action, the slottedlink-renneetion'with the bent lever above described 'prevents thedriving and supporting-wheel behind the cuiil11g-apparatus from beingthrown over, so :ls to upset the nlaehine, when ille entiing-apparatusor leluler-wheel nlceis with a rigid obstruction. e

'lhe short link between the vibrating level" alld cuilter-bar pcrnlitsthe cutting rapparatus to be lil'ted and folded without stopping thenlotion ol' the vibrating level'.

A modification ol' the above nlow'lng-lnachille is shown in figs. 10,1l, alld 12, sheet 4, iig. 13, sheet 5, and iig. 14, sheet 6.

' 'ln this mower the oscillating bevel-gear c" is jointed to agill'lbal-ring,f, instead of the hub of the vibrating lever, as ill themachine before described, alld the vibrating levell y is direct-ly andrigidly collllected wit-ll the oscillating bevel gear-wheel alld itsarms. lhc fly-wheel and shaft are thrown-under the axle to give room fortllefralne, and the fralne is-supportcd upon the axle.

I do not think it necessary to' give a further description of thismodification; the drawings su'licient'- ly explain it.

I do not consider this by any means as good a way to get up'the motionfor the cutter-bar as the method .ill which the vibrating lever is used.
